I'll try to keep this as short as possible... I'm not a heavy gamer, but I would like to be able to play newer games with reasonable settings. My current specs are as follows... HP A15010N ASUSTek NAGAMI2 Motherboard (NVIDIA GeForce 6150/nForce 410/430 MCP) 300W PSU AMD Athlon 64 3800+ (Venice) 1.5GB DDR PC3200 Dual Channel (2x512/2x256) ATI x600 All-In-Wonder 2x SATA Harddrives (200GB/160GB) DVD +/- RW Drive I've ordered this card (Was a super good deal and was time sensitive, so I bit.)... http://www.newegg.com/Product/Product.asp?Item=N82E16814121031 My questions are as follows... 1. Was this a worthwhile upgrade? 2. (a) Will I have enough power to run it? 2. (b) If not, is it possible for me to use a 2nd PSU(300W) (off to the side, jerry-rigged) just for the card?
